Lithium battery system considerations:
Lithium batteries weigh less than half of AGMs and provide more power.
Lithium lasts 5 times longer than AGMs.
Lithium batteries charge and discharge much more quickly without damage.
Initial cost of lithium is more expensive than AGM.
Lithium batteries need to stay above -4 degrees or batteries will be destroyed.
Cannot draw battery power when the lithium battery is below 32 degrees or they will be permanently degraded.
Lithium batteries cannot be above 110 degrees – high temperature operation shortens battery life.
Must consider output temperature curves for the alternator. Idling can heat up the alternator reducing output. High temperatures shorten the life of the alternator.
Consider RPMs.
Consider inverter size and operating temperature curves.

A video of my small solar project at home. It works well and im pleased with it. I am prepared for a hurricane, when power goes, i will have lights. It also runs my desk lamp, radio and modem full time. I also charge my cell phone and dig. camera battery. Although i got some of the components used, everything is available at pricesmart.
